Toronto, March 10, 2022 (GLOBE NEWSWIRE) — Doré Copper Mining Corp. (“Ltd” Also “Drecopper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is an additional high-grade from the remaining holes in the 2021 drilling campaign at the flagship Corner Bay Property at the Chibougamau Mine Camp, about 40 km by road. Announced copper results from Chibougamau, Quebec.
The 2021 drilling program totaled 41,063 meters with 43 holes (including wedge holes). Doré Copper today reports results from five of the remaining six holes in the program, further confirming the increase in deposits. These latest results are included in Cornerbay’s updated mineral resource estimates for a preliminary economic assessment (“PEA”) expected at the end of the first quarter of 2022.
Highlights of high-grade drilling
Main vein on the embankment (Figure 1)
- 6.2 meters 5.77% Cu, 0.51 g / t Au, 32.2 g / t Ag, and 1,373 ppm Mo (Hole CB-21-50)
- 2.1 meters 8.85% Cu, 0.16 g / t Au, 52.1 g / t Ag (hole CB-21-58)
- 3.7 meters 8.61% Cu, 0.16 g / t Au, 56.5 g / t Ag (hole CB-21-60)
Ernest Mast, President and Chief Executive Officer of Dre Copper, commented:Currently, there are seven holes at the southern end of the upper part of the main vane, with an impressive high-grade copper intercept that exceeds about 3% of the average copper grade of the deposit. Four of the seven holes are analyzing over 8% copper. This very high quality zone is currently about 250 meters long and 250 meters vertically and remains plunging. The addition of this zone and the recently announced zone connecting the main vane under the embankment to the lower deep lens is expected to add at least 1 million tonnes to the current high-grade mineral resources. The 45,000-meter 2022 infill drilling program at Corner Bay is underway on three rigs and focuses on upgrading estimated resources to directed resources for feasibility studies initiated after the completion of the PEA. I’m guessing. “
Corner bay drilling program
In the main vane above the embankment, today’s results (see highlights above) and previously announced 3.9 meters 8.03% Cu, 0.86 g / t Au, 42.1 g / t Ag, and 1,109 ppm Mo (Hole CB-21-55); 4.2 meters 6.18% Cu, 0.12 g / t Au, and 26.6 g / t Ag (Hole CB-21-57); 3.7 meters 9.41% Cu, 2.84 g / t Au, 36.5 g / t Ag, and 890 ppm Mo (Hole CB-21-52); Also, 2.0 m 3.34% Cu and 15.6 g / t Ag (Hole CB-21-53) are very high with a strike length of about 250 m and a vertical depth of 250 m. We have defined grade copper zones (Figure 1 and Table 1). This high-grade zone overlaps the top of the main vane under the embankment and is still plunging.
Two holes (CB-21-59 and 61) were excavated approximately 500-600 meters west of Corner Bay Mainbane and did not intersect significant mineralization. Analysis of hole CB-21-48, the deepest hole targeting the main vane under the embankment, is pending. The hole crossed about 60% chalcopyrite over a meter.
The 2021 drilling program continued to expand the copper-gold mining activity of the corner bays in three areas of the deposit (Figure 2), with a total strike length of over 1,100 meters.

- The actual width of the intersecting structures is estimated to be about 55-60% of the downhole width.
Corner bay deposit
Mineral resource estimates for October 6, 2021 indicate that the Cornerbay deposit contains 2.66 Mt of labeled resources at 2.68% Cu, 0.26 g / t Au, 4.54 containing 157 million pounds of copper and 22,000 ounces of gold. Contains estimated resources for Mt. Includes 320 million pounds of copper and 39,000 ounces of gold at 3.20% Cu and 0.27 g / t Au, based on a 1.3% Cu cutoff grade and a copper price of $ 3.75 per pound (see). Technical report dated November 10, 2021).2..
The Cornerbay deposit is hosted by the intrusive rock dre complex on the south side of the Chibougamomo anticline. The diorite embankment north-northeast of the area also cuts out the area. Several important shear bands have been identified in this area, directed north-south and northwest-southeast. The corner bay area is characterized by copper porphyry-style mineralization and copper mineralization in the shear bands commonly associated with embankments associated with Chibouga mapleton.
Drilling and quality control
We use Miikan Drilling as a drilling contractor. Miikan is a joint venture between Chibougamau Diamond Drilling Ltd., Ouje-Bougoumou’s First Nations community and Mistissini’s First Nations community, both located in the Eeyou Istchee region.
Sample preparation and analysis took place at AGAT Laboratories in Mississauga, Ontario. Samples were weighed, dried, ground to 75% through 2 mm, split into 250 g and ground to 85% through 75 microns. Next, a sample Au (50 g) fire assay and a 43 element tetraacid digest ICP-OES finish were performed.
QA / QC is done in-house by Doré Copper Geologists under the supervision of the Exploration Manager. Check samples inserted in the sample batch (blank and standard – 4% of total sample, 2% more core duplication) are validated against the certification value and pass if within 3 standard deviations of the certification value. Is considered. .. Duplications are evaluated mutually to determine the distribution of mineralization (nuggets). If there is a large discrepancy in the check sample, you will be asked to reanalyze the entire batch.
